To ILL whom t mag/ 'cohcern:

Be it known that I, ALFRED BRYANT DAY, citizen ofl `the United States, residing at Knoxville, in the county of Knox and State o f Tennessee, have invented certain new and useful Improvements in Mining-Car Wheels, of which the following is a specification, reference being had therein to the accompanying drau'fing. j

This invention relates Yto improvements in carvwlieels, and has to dealV more particularly with Wheels designed for'mining'car service, though not limited to this use.

The primary object of the invention is to reduce to a minimum, the friction and incident Wear'between the wheel hub 'and' its as- It is a matterr of. Acommon ter under consideratiom'vvherein thel Wheels are'loosely mounted uponthe` axle, the end thruston the Wheel in rounding curves is considerable, andit1li-afs Abeen;suggested to takev care ofl thisiiend thrust -in/dierenty Ways,usuzy1lly` by allovving they inner end of the .hub "to contact? with .the :side of ythe pedestal box, orto provideanfabutment on the inner surfaeeof the hu'blc'ap lWith which the end of the .axle Would contact. In either.

' ease', the constructionthas .not proven altotioned type of wheel,rconsiderable 'frictionr between the hub and pedestal resulted in ai great deal of' objectionable Wear at this gether satisfactory, since, in the first menpoint, Whereas the. saine objectionto -friction and wear Was'` manifest in' that type of construction wherein the axle abutted V against tliejend of the hub.v Ithas also been propo'seclfto` lprovide a shoulder4 orv the llike on theiihub, adjacent its outer end, andv to' turn-down the'end of the axle to a relatively small diameter to provide ashoulder on the vaxle vto engage theend of the hub. When. relatively 'small axles are employed, this' should'enon the axleivvill, of necessity, bevery small, or else the smaller diameter ofV the end oftheaxle Wouldbe devoid .of the necessary strength to withstand the Wear A and strain.

The above land other objections incident to the use of prlo-r constructions along this line have led to the present invention, which,v

- generally speaking, involves novel, eicient,

and economical means'for providing against the friction and Wear ofthe hub andfpedfs estal dueto the end thrust of the Wheel, espe'-V eialiy in goingaround curvesaf 1 Specification of Letters Patent.

Within the l hub receiving part of the pedestal in cngageuzent with the packing` 3, and otherwise spaced throughout from the Wall of the hub receiving part. The hub 5 conveniently has an integral cap member 7, with an axle opening or recess 8. v

9 is an axle` preferably fixed against rotation and projecting through the hub receiving part of the pedestal, thence through the hollour hub to a point beyond the cap thereof. The projecting end 9a of the axle has a reduced diameter relative to the body thereof, and the diameter of the projection 9 is less than the diameter of the opening 8 of the hub cap, thereby providing an intervening space. The body portion of the axle at its point of juncture with the projecting end thereof, of reduced diameter, provides a shoulder 10 spaced inwardly from the inner surface of the hub cap.- Positioned on .the axle in the space between the shoulder 10 and inner surface of the hub cap 7 is a suitable member or members for receiving the end thrust of the Wheel hub in an in- Ward direction. The said member `refer- .ably takes the form of an annularco lar 12,

of metallic formation, and this collar may have a tubular body part 13 ofa lengthto project through the hub cap to a point adj acent the end of the axle, and. substantially filling the space between the Wall of the opening 8 and the periphery of the axle.

A common means preferably performs the double function of securing the collar 12 to the axle and providing 'for the end thrust of the Wheel in an outward direction, the said means takingl the form of a suitable detachable pin 14 projecting through the axle and tubular part 13 ofthe collar 12, and overlying the outer surface of the hub cap. From the constructionl thus described it will be appreciated that the 'hub is spaced from the axle as Well as the pedestal niember throughout, thus overcomingv the usual .frictlon between these parts. 'l ,also"preferably interpose between the annular collar 12 and hub cap 'i a suitable friction receiving' part 15 conveniently taking the form of a metallic disk-shaped washer. It has been seen that the collar 12 is secured through its tubular extension 13 to the axle and therefore will remain stationary relative to the rotatable Wheel sleeved `ipon the axle, and if desired, suitable means may be provided for removably securing thegvasher to one 0f the parts comprisingr the hub and collar. In the preferred construction, the collar is removably secured to the hub cap' through the medium of one or more pins or dowels 15a adapted to fit rWithin recesses 151 in the inner face of the hub cap. By this means the collar is adapted to rotate with the Wheel hubLand 'any friction at this point Willtake placel between the adjacent surfaces of the collar 12 and washer 15. A. similar collar or Washer 1G is preferablj," loosely positioned on the tubular extension '1.3 to the outside of the hub cap and at a point between said hub cap and the securing pin 'l--l-. forms afriction receiving' element for the outer surface of the huh capin the cut-Ward thrust of the iyheel. The hub cap is preferably provided with an annular recess 17 adapted to receieve a suitable packing, such as felt, 19, conveniently held in place in any desired manner as by a spiral spring 20.

Roller bearings 21 are preferably arranged in the space between the hub and axle and the inner surface of the hub conveniently has a removable lining 22 to be engaged bythe rollers. The rollers have at opposite ends, projecting pintles 21a. A suitable col lar 23 having an annular fiange 24 is secured to the inner surface .of the hub adjacent its inner end as by bolts 21a, and an loffset annular flange 25 adapted to overlap the projecting pintles of the rollers at this end. I preferably take advantage of the annular collar 12 for supporting the opposite end of the rollers, and to this end I form an annular cut out part 26 forming a shoulder or abutment 2T for the end of the rollers,

and a shoulder or abutment 2S for the end of the pintles.

One or more lubricating openings 29 may be provided, as desired, the same being normally closed by threaded nuts 30.

The constructionand operation of the de-A vice, from the description, when considered in connection with the accompanying drawings, 1s believed to be clear. It vvlll be seen that the Wheel may be readily removed, andthis Without displacing the rollers, by simply removing the securing pin .141 Vlhen in position von the axle the Wheel hub is devoid of all frictional Contact with either y the axle or pedestal member, the end thrust of the hub being taken care of in one direcM tion through the medium of the securingF pin lai. and washer 16, and in an opposite direction by the washer 15 and collar 12. -lither washer 15 or 1G, or the thimble comprising the collar 12 and tubular extension' 13 may be removed at will and replaced as occasion demands.

'it may be desirable in some instances to provide in lieu of the Washers 15 and 1G, a' suitable anti-friction and thrust bearing, such as illustrated in the modiiedtype of washer disclosed in Figf. "till further minor changes may be made inthe arrangement and construction of parts without departing from the spirit of the invention. c
